The error I get is the classic "Radio did not ACK first command".
I have chirp working just fine with other chinese radios including BF-F8HP, BF-T1 and UV-9R.
The BF-F8HP / UV-5R cable I have, and the UV-3R cable both appear to use the same Prolific chipset (the BF-T1 and UV-9R cables show up differently)...

From what I've read possible issues could include a driver problem or defective cable. But to my mind, given the chipset appears to be the same and I have the BF-F8HP cable working, I would have thought that the UV-3R cable would work as well?
Any ideas for how else to troubleshoot this? Is there anything that's worth trying before I give up and order a different cable? (If not, recommendations for a reliable source for a cable for the UV-3R would be welcome.)
Thanks,
